The perfect key chain set for friends, sisters or pets and their owners. The cut out hearts match when put together and can be stamped with Best Bitches Best Buddies Or words of your choice The pair each have a name stamped onto a tiny heart . I'm happy to work with any wording though so just add a note when ordering. Stamped onto aluminium shapes, aluminium being non tarnish and non allergenic and held together with extra strong stainless steel rings.
